As he has done nothing wrong, Beaulieu doesn't want to kill Yannick and eventually agrees to let him go if he wins a game of chess against him, Beaulieu having never lost a game in his life so far. They play chess constantly, but Yannick never wins, though he rattles Beaulieu by once managing a draw. After Beaulieu's wife and daughter finally stand up to Beaulieu, they free Yannick. But Yannick has gone mad sitting locked in the room playing chess games against Beaulieu and doesn't leave, believing that the only option to stop Beaulieu is to win against him. In the final showdown the two play a chess game in the cellar, where Beaulieu has conserved all of his victims and placed them as pieces on a giant chessboard. During the game, Beaulieu's little stepdaughter enters the cellar and witnesses her dead mother placed as a piece on the chessboard. She is then shot accidentally by Beaulieu, which renders him catatonic. The police arrive, free Yannick and arrest Beaulieu. Four months later Yannick is still madly obsessed with the interrupted chess game, so thoroughly consumed by the thought of the final position that he alienates himself from his girlfriend.
